Rift Valley Sand and Gravel Pit have contracted to provide topsoil for three residential housing developments. Topsoil can be supplied from three different “farms” as follows: Farm Weekly capacity (cubic yards) A 100 B 200 C 200 Demand for the topsoil generated by the construction projects is: Project Weekly demand (cubic yards) 50 150 300 The manager of the sand and gravel pit has estimated the cost per cubic yard to ship over each of the possible routes: Cost per cubic yard (in Birr) From Project #1Project #2Project #3 Farm A 4 2 8 Farm B 5 1 9 Farm C 7 6 3 A. Formulate a balanced transportation problem in a transportation tableau B. Find minimum transportation cost using Northwest corner, least cost and VAM methods

Who is better at multi-tasking? in business, employees are often asked to perform a complex task when their atten-tion is divided (i.e., multi-tasking). human factors (may 2014) published a study designed to determine whether video game players are better than non–video game play-ers at multi-tasking. each in a sample of 60 college stu-dents was classified as a video game player or a non-player. participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersec-tion. the simulator was designed to have cars traveling at various high rates of speed in both directions. during the crossing, the students also performed a memory task as a distraction. two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). the researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. “these results,” say the researchers, “suggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task”

Miller mfg. is analyzing a proposed project. the company expects to sell 14,300 units, plus or minus 3 percent. the expected variable cost per unit is $15 and the expected fixed cost is $35,000. the fixed and variable cost estimates are considered accurate within a plus or minus 3 percent range. the depreciation expense is $32,000. the tax rate is 34 percent. the sale price is estimated at $19 a unit, give or take 3 percent. what is the net income under the worst case scenario?
